SPRING WHEEL.

Application filed March 20, 1924.

To all whom t may concern:

Be it known that we, DAVID E. FULTZ and Oris L. Gerco, citizens of the United States, residing at Madill, in the county of Man shall and State ot Oklahoma, have invented certain new and usetul improvements in Spring lheels; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to vehicle wheels and has tor its object to provide a wheel which neutralizes shock and vibration and practically possesses all the advantages of a wheel equipped with a pneumatic tire, but which is tree from puncture, blowout, rim cut and like troubles incident to pneumatic tires.

@ther objects and advantages will be apparent and suggest themselves as the nature ot the invention is understood.

While the drawings illustrate an embodiment ot' the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the term, proportion and minor details of construction may be resorted to without departing from the spirit of the invention.

Referring to the accompanying drawings torming a part ot the application:

Figure l is a side view of a spring wheel embodying the invention,

Figure 2 is an enlarged sectional view on the line 2---2 ot Figure l., and

,Figure 25 is an. enlarged sectional view onv the line ll ot Figure l..

Correspollding` and lile parts are reiterred to inthe following description and designated in the severa-l views ot the drawings by like reference characters.

The tire l is preferably hollow and is provided with an annular web 2 held in place by yokes 3 which embrace the inner side of the tire l and which have inwardly disposed lugs ul to which the web 2 is bolted. The yokes 3 may be attached to the tire l by means ot bolts 5, or in any preferred way, and the annular web 2 may be attached to the lugs t by means ot bolts 6 or in any preferred way.

A spider or hub center 7 has its outer portion loosely fitted between spaced portions 2a oit the annular web 2 and this spider has a limited eccentric movement. Bolts 8 are disposed between the projecting elenients 7 i* Serial No. 700,658.

ot the spider or hub center 7 and limit the movement thereof and also have the outer ends of helical springs 9 connected thereto, the inner ends oi' said springs being connected to the spider or hub center. Spacing blocks l2 are mounted on bolts 8 and are seated between the spaced portions 2a. The springs 9 are normally under tension and are adapted to sustain the load and compensate `tor shock and vibration. The hub l0 is secured to the spider or part 7 and to the brake drum 11 by means of screw bolts 13. As shown the spring-sb are terminally connected to bolts 8 and 18.

\ It will be understood from the foregoing and the drawings hereto attached that the invention results inthe provision of a supporting wheel of simple construction, ot few parts and capable of neutralizing shock and vibration.

Vihat is claimed is:

l. A vehicle wheel comprising a tire, an annular web within the tire and attached thereto, a spider within the annular web and having its outer portion comprised between spaced portions thereof, and substantially radial spring connections between the spider and web.

2. A vehicle wheel comprising a tire, an annular web within the tire, fittings connecting the web and tire, a spider having its outer portion comprised between spaced portions oit the annular web, tastenings extending between thc spaced portions of the spider and supported by the spaced portions ot the annular web, and substantially radial spring connections between the annular web and spider.

3. A vehicle wheel having a web provided with a recess, a spider having projections extending into the recess, tastening elements extending through and laterally beyond the web intermediate said projections, hub means associated with said spider, fastenings securing said means thereto and extending laterally beyond said means, and substantially radially arranged spiral springs connected to the extensions oit said fastening elements and said iastenings.

In testimony whereof we ailix our signatures in presence of two witnesses. A
